Open ureterolithotomy and pyelolithotomy used to be first line therapy for treating kidney and ureteral stones. With the advent of shockwave lithotripsy, open stone surgery became less prevalent, but once ureteroscopy became more prevalent, open stone surgery became all but extinct. Advances in smaller, more flexible endoscopes and improvements in intracorporeal lithotripters, ureteroscopy has become a mainstay of therapy for kidney stones. The holmium:YAG laser can be utilized through flexible instruments and fragments any stone no matter what it is composed of...

BACKGROUND AND IMPORTANCE: As the use of flow-diverting stents (FDSs) for intracranial aneurysms expands, a small number of case reports have described the successful treatment of blister aneurysms of the internal carotid artery with flow diversion. Blister aneurysms are uncommon and fragile lesions that historically have high rates of morbidity and mortality despite multiple treatment strategies. We report a case of rebleeding after treatment of a ruptured blister aneurysm with deployment of a single FDS...

Endovascular treatment of a giant extracranial internal carotid aneurysm by a stent graft implantation was unsuccessful due to a high flow leak directly through the stent graft's coating. The problem was solved deploying a second stent graft inside the previously implanted one resulting in complete exclusion of the aneurysmal sac and patent carotid lumen preservation. The review of the literature did not provide a case using this endovascular strategy. Follow-up for more than 12 months, using CT angiography, showed confirmed aneurysmal exclusion and carotid patency and no clinical complications have been detected...

: Ameloblastoma is the most common benign odontogenic tumor of the jaw, and expansional growth of a huge untreated ameloblastoma can result in disturbances in facial aesthetics and function, such as difficulty with mouth opening, swallowing, chewing, breathing, neurologic deficits, and pathologic fractures. Radical wide resection with safety margins and subsequent reconstruction is generally recommended. A fibular free flap (FFF) is commonly used to reconstruct the mandible in order to adequately restore both aesthetic appearance and function...

OBJECTIVE: To compare total percutaneous access using preclose technique with femoral artery cut-down in endovascular aneurysm repair (EVAR) and assess the safety and feasibility of preclose technique. METHODS: In the study, 81 cases undergoing EVAR from Dec. 2011 to Nov. 2014 in Peking University People's Hospital were retrospectively reviewed. Preoperative CT angiography (CTA) showed presence of infrarenal abdominal aortic aneurysm or descending aortic aneurysm in all the cases...

INTRODUCTION: Tandem occlusion resulting in acute ischemic stroke (AIS) is associated with high morbidity and mortality and a poor response to thrombolytic therapy. The use of endovascular strategies for tandem stroke cases results in an improved outcome for this subgroup of patients. We present two cases with a pattern of tandem occlusion consisting of proximal obstruction at the origin of the common carotid artery (CCA) with concomitant intracranial occlusion treated by endovascular techniques...

BACKGROUND: The influence of acute cerebral ischemic lesions (CILs) on the revascularization outcome of symptomatic carotid stenosis has been scarcely investigated in the literature. This study evaluated the effect of CILs and their volume on the results of carotid revascularization in symptomatic patients. METHODS: All patients with symptomatic carotid artery stenosis who underwent carotid endarterectomy (CEA) or carotid artery stenting (CAS) between 2005 and 2014 were considered...

OBJECTIVE: To evaluate the technical aspects and short-term clinical results of stent placement for chronic occlusion of a filter-bearing inferior vena cava (IVC) in patients with severe post-thrombotic syndrome (PTS). METHODS: A retrospective analysis of 24 patients with severe PTS associated with occlusion of a filter-bearing IVC treated by stent placement was conducted at a single institution from January 2010 to December 2014. Patient-reported quality of life and limb Villalta scores were evaluated before and after treatment by questionnaire and clinical examination, respectively...

BACKGROUND: How to choose the proximal landing zone in endovascular interventions for a patient with a patent retrograde false lumen in dissection of the ascending aorta and aortic arch remains unclear. This study sought to report the safety and efficiency of inducing thrombosis of the retrograde false lumen to enhance a proximal landing zone to treat retrograde type A aortic dissection. METHODS: This study included 9 patients with retrograde type A aortic dissection treated with a 2-stage operation strategy between January 2015 and January 2016...

The angioplasty of chronic total aortoiliac occlusion using transfemoral is controversial. From March 2014 to December 2015, four consecutive patients (4 males; mean age 58.2±6.8 years; age of range 51-65 years) underwent angioplasty and stenting of TASC-D occlusion. In all the cases, we failed to cross from femoral approach. On switching over to left brachial access, angioplasty was done successfully in all. There was no procedural site complication or clinical evidence cerebral thromboembolism. Self-expandable stents were implanted in all with adequate pre and post dilation...

Carotid artery dissection (CAD) is a frequent cause of stroke, accounting for up to 25% of all ischemic strokes in young and middle-aged patients.(1,2) It may be traumatic or spontaneous, with multi-factorial etiology. A tear in the arterial wall causes intrusion of blood within its layers, producing intra-luminal stenosis, or aneurysmal dilatation.(3) Thrombo-embolism arising from this anatomic disruption has been postulated as the essential stroke mechanism in CAD.(4) Bilateral internal carotid artery dissection (ICAD) has been rarely reported...

Coronary artery stent infection has been reported with both bare metal stent and drug eluting stent and can present as mycotic coronary artery aneurysm, pseudoaneurysm, myocardial abscess, pericarditis or exudative effusion. Infection at the site of coronary stent implantation is rare and is believed to result typically from either direct stent contamination at the time of delivery or transient bacteraemia from access site. Introduction of drug-eluting stent (DES) has led to a marked reduction in the problem of in-stent restenosis across all patient subsets and lesions complexities...

Very late stent thrombosis (VLST) has been recognized as a class effect of 1st generation drug eluting stents (DES) implantation. Although rare, VLST has been reported between 1 and 4 years after DES implantation. Very very late stent thrombosis (VVLST) occurring more than 5 years after DES implantation is extremely rare. We report the first case of a VVLST from India occurring 3465 days (9.5 years) after DES implantation with a brief discussion on its pathogenesis and prevention.

Very late stent recoil is a rare albeit recognized phenomenon leading to subsequent in-stent restenosis. Angiography alone may not be adequate in making the diagnosis, and intravascular imaging with optical coherence tomography (OCT) is far superior in confirming the diagnosis and guiding subsequent management. We describe a case with interesting coronary angiogram and OCT images demonstrating very rare diagnosis of the late stent collapse. These images provide a valuable insight into a novel mechanism responsible for late target lesion failure...

Thirty-nine year male had a history of road traffic accident with polytrauma. At emergency room he started having chest pain with ventricular tachycardia. He was subsequentially diagnosed with right coronary artery dissection secondary to blunt trauma which is an extremely rare cause of inferior wall myocardial infarction. After some dilemmas, he was ultimately treated with intravascular ultrasound guided coronary angioplasty with stenting and had an uneventful recovery.

A 62-year-old male was undergoing treatment of NHL with bone marrow involvement with thrombocytopenia. After 15min of starting of IV infusion of rituximab, he started having severe retrosternal chest pain, diagnosed as acute ST elevation inferior wall MI. Patient was pre-loaded with dual anti platelets. Coronary angiogram showed 100% occlusion of proximal RCA. Thrombosuction of this culprit RCA revealed underlying 90% stenosis. After that, PCI with balloon angioplasty of RCA was done. The procedure was terminated in the view of successful balloon angioplasty with good TIMI flow...
